> As the {{ProvidedDatanodeStorageInfo}} is shared across multiple Datanodes, it's block
count shouldn't be set to 0 (in {{DatanodeDescriptor.updateRegInfo}}) when any one Datanode's
registration info is updated. This prevents {{processFirstBlockReport}} from being called
multiple times for {{ProvidedDatanodeStorageInfo}}.
